**Problem:**If you push a 3kg book across your desk at a constant speed of 2 m/s with a force of 7N, what is the net force that acts on the book?- 0N- 7N- 21N- 42N**Explanation:**To solve this problem, it's important to understand that when an object moves at a constant speed, the net force acting on it is zero. This is because any applied force is balanced by opposing forces like friction.**Key Concepts:**1. **Net Force:** The total force acting on an object after all opposing forces are considered. It determines the motion of the object.2. **Constant Speed:** Indicates that the forces are balanced; the net force is 0N.Given:- Mass of the book = 3kg- Speed of the book = constant 2 m/s- Applied Force = 7NSince the book moves at a constant speed, the frictional force exactly balances the applied force. Therefore, the net force is 0N.

Listen> Read the scenario. A cyclist is riding his bike at a constant speed of 5 m/s, and experiences a frictional force between the bike and sidewalk of 100 N. The cyclist then changes his speed to 10 m/s. What effect does this increase in speed have on the frictional force between the bike and sidewalk? The frictional force doubles because when speed increases frictional force also increases. The frictional force between the bike and sidewalk stays the same because speed does not affect frictional force. The frictional force becomes half of what it was because when speed increases, frictional force decreases. The frictional force increases, but does not double because although friction increases with increasing speed, it does not increase as fast. Next >
